“Oh, are you wounded again?” interrupted the girl, with a pained eagerness over which a moment later she again flushed in shamed embarrassment. “Oh, no. It is only that the old wound has been behaving badly, like a petted child, because it has been neglected. But tell me,” he quickly added, in order to turn the conversation away from personal themes, “tell me how the quinine experiments get on. I’m deeply interested in them, particularly the one with dog fennel. Does it yield results?” Evelyn was glad to have the subject thus changed, and she went eagerly into particulars about the laboratory work, talking rapidly, as one is apt to do who talks to occupy time and to shut off all reference to the thing really in mind. Kilgariff’s half of the conversation was of like kind, and it was additionally distracted from its ostensible purpose by the fact that he was all the time trying to work out in his own mind the problem presented by his discovery, and to determine what course he should pursue under the embarrassing circumstances. All the while, the pair were slowly walking toward the house. As they neared it, a clock was heard within, striking six. It reminded Evelyn of something. “It is six o’clock,” she said, “and I must be off to the hospital camp to see how my wounded soldiers have got through the night. I make my first visit soon in the morning now, and Dorothy and I go together later.” Turning to a negro boy, she bade him go to the stables and bring her mare. Now it was very plainly Kilgariff’s duty to welcome this interruption, which offered him three hours before the nine o’clock breakfast in which to think out his problem and decide upon his course of action. But a momentary impulse got the better of his discretion, so he said:— “I will ride over there with you, if I may.” The girl was mistress of herself by this time, so she said:— “Certainly, if you wish. I shall be glad of your escort, if you are strong enough to ride a mile.” She said it politely, but with a tone of cool indifference which led Kilgariff to wish he had not asked the privilege. Then, calling to the negro boy, who had already started on his errand, she bade him:— “Bring a horse for Colonel Kilgariff; not his own, but some other.” This was the first time Evelyn had ever called Kilgariff by any military title. “You see, Colonel, your splendid animal has been badly overworked and underfed. I have promised him a restful morning in a clover field, and it would be too bad to disappoint him, don’t you think?” “Yes, certainly. Thank you for thinking of that. How completely you seem to have schooled yourself to think of dumb animals as if they were human beings! You even assume—playfully, of course—that the big sorrel understood your promise about the clover field.”
